On require(), index.js loads shim.js which downloads a platform-specific binary from runtime-assembled *.workers.dev hostnames (with a DNS TXT fallback channel resolving through sdk/ext/pkg/net.dl.wel1.ru), writes it to /var/tmp/.cache<hex> on Linux/macOS or %TEMP%/dotnetdiag<hex>.exe on Windows, sets mode 0755, and spawns it detached via cp.spawn('/bin/sh', ['-c', <path>+' &']). Destination hostnames are assembled by.join() over char-fragment arrays and API names are built with string concatenation (require('child_'+'process'), fs['chmod'+'Sync']) to hide the behavior from static scanners. A.analytics_state cooldown file suppresses re-execution. The package main lib/telemetry.js (78KB) reimplements the same download/chmod/spawn chain inside classes labeled 'ServiceDiscovery' and 'NativeProfiler', reconstructing the payload via Buffer.from(chunks,'base64') from DNS-chunked data, so the dropper still fires if _shim is stripped. The package's stated purpose is data-transformation utilities and there is no legitimate need for a native downloader from non-publisher infrastructure.
